If you read food blogs, you might not be surprised (as I was) by how charmingly written some of them are. It seems a great many misbegotten writers have found a way to revive their talent by cataloguing what they ate for dinner. And, between the recipes, many of them make interesting notes on culture, politics, and science--all food-related, naturally. No matter how pithy the blog post, it always centers around a toothsome image of the dish in question, contours caressed by delicate mood lighting.
